Photoshop CS5: Trickery and FX is very well done and laid out. Each chapter including the first — which in many books would just be a dry intro chapter — is a tutorial that does not just tell you what you need to do, but actually shows you what to do.
After the first chapter, there is an image showing the completed work that you are about to work with as well as a short set of bullet points of what skills that you will gain from the chapter. From there you are shown, step-by-step, exactly how to create each image with screen shots at most every step. At the end is an image of what the completed work should look like, as well as a refresher of what you have learned.
Also included with the book is a DVD that contains all of the content and image files that you will need to complete the tutorials as well as bonus videos that feature additional tutorials. If you want to take advantage of the new features within Photoshop CS5, especially the new brushes and 3D tools, then I would very highly recommend Photoshop CS5: Trickery and FX .
